Answer:
56.7 m³
Explanation:
The radius of the circular area covered by the spill is 4.25 km
You can find the area covered by the spill by applying the formula for area of a circular surface
A=π×r² where π=3.14 and r=4.25km
A= 3.14×4.25² = 56.72 km²
Remember the total area is on average at 1 micron (1μm) thick.This is to say
1μm=1m³
So the minimum volume of oil covering the ocean surface in meters will be;
Change km² to m²
56.72 km²= 56.72×1000000=5.67×10⁷ m²
Finding the volume;
Volume = Area * thickness
Volume= 5.67×10⁷ m² * 1× 10⁻⁶ = 56.7 m³
Minimum amount of oil that was spilled is 56.7 m³
Unlike a ball, an atom doesn't have a fixed radius. The radius of an atom can only be found by measuring the distance between the nuclei of two touching atoms, and then halving that distance... Does that answer your question?
Answer:
Time interval;Δt ≈ 37 seconds
Explanation:
We are given;
Angular deceleration;α = -1.6 rad/s²
Initial angular velocity;ω_i = 59 rad/s
Final angular velocity;ω_f = 0 rad/s
Now, the formula to calculate the acceleration would be gotten from;
α = Change in angular velocity/time interval
Thus; α = Δω/Δt = (ω_f - ω_i)/Δt
So, α = (ω_f - ω_i)/Δt
Making Δt the subject, we have;
Δt = (ω_f - ω_i)/α
Plugging in the relevant values to obtain;
Δt = (0 - 59)/(-1.6)
Δt = -59/-1.6
Δt = 36.875 seconds ≈ 37 seconds
It’s A because energy passes freely through the atmosphere and is absorbed by earths surface.

Please give me brainly,
The thermal energy of an object depends on three things: 4 the number of molecules in the object 4 the temperature of the object (average molecular motion) 4 the arrangement of the object's molecules (states of matter). The more molecules an object has at a given temperature, the more thermal energy it has.
